CA5420A
0.5MHz, Low Supply Voltage, Low Input
Current BiMOS Operational Amplifiers
The CA5420A is an integrated circuit operational amplifier that
combines PMOS transistors and bipolar transistors on a single
monolithic chip. It is designed and guaranteed to operate in
microprocessor logic systems that use V+ = 5V, V- = GND,
since it can operate down to
±
1V supplies. It will also be
suitable for 3.3V logic systems.
The CA5420A BiMOS operational amplifier features gate-
protected PMOS transistors in the input circuit to provide very
high input impedance, very low input currents (less than 1pA).
The internal bootstrapping network features a unique
guardbanding technique for reducing the doubling of leakage
current for every 10°C increase in temperature. The CA5420A
operates at total supply voltages from 2V to 20V either single or
dual supply. This operational amplifier is internally phase
compensated to achieve stable operation in the unity gain
follower configuration. Additionally, it has access terminals for a
supplementary external capacitor if additional frequency roll-off
is desired. Terminals are also provided for use in applications
requiring input offset voltage nulling. The use of PMOS in the
input stage results in common-mode input voltage capability
down to 0.45V below the negative supply terminal, an important
attribute for single supply application. The output stage uses a
feedback OTA type amplifier that can swing essentially from
rail-to-rail. The output driving current of 1.0mA (Min) is provided
by using nonlinear current mirrors.
This device has guaranteed specifications for 5V operation
over the full military temperature range of -55°C to 125°C.
The CA5420A has the same 8 lead pinout used for the
industry standard 741.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
